Uninstalling the Software

Procedure

1. Uninstall OmniShuffle.

   cd /home/ockadmin/BoostKit-omnishuffle_1.4.0/omnishuffleUtils/bin
   sh ock_uninstall.sh

   

2. Optional: Remove the certificate and key files.
   

   If the security feature is enabled, remove the Spark and ZooKeeper users' OmniShuffle-related certificate and key files.

   1. Run the echo $OCK_HOME command to check whether the OCK_HOME environment variable exists. If not, set it to the OmniShuffle installation directory (/home/ockadmin/opt/ock by default). After confirming the OCK_HOME environment variable, perform the following operation to set LD_LIBRARY_PATH:

      export LD_LIBRARY_PATH="${OCK_HOME}/ucache/${OCK_VERSION}/${OCK_BINARY_TYPE}/lib/common:${OCK_HOME}/ucache/${OCK_VERSION}/${OCK_BINARY_TYPE}/lib/common/openssl:${OCK_HOME}/ucache/${OCK_VERSION}/${OCK_BINARY_TYPE}/lib/mf:${OCK_HOME}/ucache/${OCK_VERSION}/${OCK_BINARY_TYPE}/lib/datakit:${OCK_HOME}/ucache/${OCK_VERSION}/${OCK_BINARY_TYPE}/lib/common/ucx:${OCK_HOME}/ucache/${OCK_VERSION}/${OCK_BINARY_TYPE}/lib/common/ucx/ucx:${LD_LIBRARY_PATH}"

   2. Remove the key file first, using a Spark user as an example:

      .${OCK_HOME}/ucache/24.0.0/linux-aarch64/bin/kmc_tool all --secureEraseAllKeystore ${SPARK_HOME}/huawei/ock/security/pmt/master/ksfa ${SPARK_HOME}/huawei/ock/security/pmt/standby/ksfb

   3. Remove the OmniShuffle certificate file.

      rm -rf ${SPARK_HOME}/huawei/ock
